Every 12 Months - Swegon CLASS UNIT TAC 5 Manuel D'installation Et De Maintenance

5.2 Every 12 months

1. Check for any alarm indicated on the control device. In case of alarm refer to control manual.
2. Check the state of filter clogging. The control device allows to set a pre-defined 'filter clogging' threshold (refer to
installation manual). If need be replace filters. Filters that are too clogged can generate the following problems:

Insufficient ventilation

Excessive increase of fan rotation speed, creating excessive sound level

Excessive power consumption (power consumption will increase exponentially to an increase in pressure
drop, for a constant airflow)

A damaged filter allows unfiltered air to enter heat exchanger (risk of clogging) and into ventilated room.

3. Inspection and cleaning of the inside of the unit:
- Vacuum clean any accumulation of dust in the unit.
- Inspect and gently vacuum clean if need be the heat exchanger. Use brush accessory to protect fins.
- Clean the possible condensation marks and possible accumulations in the drain pan.
- Clean the inside of the bypass. To access interior of bypass it is necessary to force-open it, proceed as follows:
jump terminals IN4 and +12V on the CB4 TAC5 DG circuit board. The bypass is now open, independently of
temperature conditions.
- Remember to remove jump between terminals IN4 and +12V once cleaning of bypass is done
4. Fan maintenance:
Check again if power supply is shut down and fans are not running.
Check cleanness of fan. Clean if necessary, be careful not to alter balancing of the fan wheel (do not remove
balancing clips). Dismount fans if necessary.
5. Check airtightness of unit:
Particularly check that side access panels are well closed and that airtightness seals are in a good state. Replace
if necessary.
